I keep going back to
DVDShrink for compressing my backups to fit a 4.7gb disc. I generally use the "smooth" option during compression, and it gives a much higher quality video/resolution than
DVDFab Platinum. It would be nice if DVDFab had the same high quality compression so backups could be done in one program. Comparing the two, DVDFab has a lot more pixelation and it's easily seen. DVDShrink, on the other hand, is able to compress a dvd 50-60% and it is barely noticeable. Maybe the DVDShrink developer would allow you to incorporate his program?
